How to access modem configuration page while bridged?

[xaitmi]

Hi.

My RT N66U is currently bridged with my modem.

I want to be able to view the modem configuration/status page without having to manually plug my laptop directly into the modem. I was viewing the instructions from here and was wondering.

How do i determine my modems IP for step 1.

And if there was a way to set all this up directly from the routers settings, since it's been about 2 years since truva made those scripts

Here is the post I am referring to.

Hi,

In my case the modem has a fixed IP address but is only accessable when connecting directly to it with a LAN cable: My provider manual says "Open a Web Browser and type http://192.168.100.1 in the URL address field."

The details come from your Internet Service Provider or (if you are lucky) you find the information online with the vendor of your modem.

You also need find out login and password for the modem...

The ISP usually provides some documentation where they mention the IP address. You can also connect your laptop to the modem and see if you get an IP address via DHCP.

For example my modem by default is at 192.168.1.1.

A simple and non permanent way of doing this is to telnet or SSH into your router and input ip addr add 192.168.1.254/24 brd + dev eth0

Now you can access the modem at 192.168.1.1.

This is gone after a reboot, for a permanent setting you need to use scripts.

With u-verse there default address was 192.168.1.254. Even though I am set up in DMZ PLUS (bridged), if I enter that address into my browser I get the residential gateways' web page without having to write rules to the routing table.

Hi, thanks for your replies guys.

My problem is that I have a Rogers Home Gateway modem, so it's a modem and router 2 in 1.

I put it into bridge mode to disable the router function of the modem, after that all it gets assigned is a public IPV4 address.

I then attach the modem to my ASUS router.

Here is an ifconfig from the router. Any help would be much appreciated.

As you can see, my modem's public iPV4 is on eth0.

Hi,

I have the same setup (from a different ISP and modem) and still it works as outline in my above posting!

Yeah I can access my modem status page if I connect to it directly via an Ethernet. I was looking for a way to avoid that, and just be able to type in an IP address.

But it looks like that is not possible. It is unfortunate that ISPs force us to use these 2 in 1 Gateway Modems.

Different modems have different ways of "bridging". According to my modem's manual, once you put it in bridge-mode, the web-interface is no longer accessible.

If your modem's web-interface happens to still be accessible, the only tutorial I have personally encountered is for pfSense; https://doc.pfsense.org/index.php/Accessing_modem_from_inside_firewall

I have no idea if this same functionality can be achieved with Asuswrt.

Very true. Some may turn off the local address when it hands the public IP to the bridged local device. In the case of 2Wire and modern Motorola devices they don't seem to do this thus you are able to get though the personal router. On some of the less "expensive" DSL devices when they are bridge don't provide any access. With those devices the only option is a lan connection.
